Lol yeah, I did that a lot with my first! I couldn't even give them away to friends with babies in good conscience, so it was great being able to get the things I really needed with that money.
When I got those types of products, I took them back to places like Babies r us, Walmart, etc. or wherever they were carried... and you could take it without a receipt and get store credit.
@mamalamadingdong I don't know what to do with all this bathtime stuff I got from my baby shower now! I feel like I'm contributing to chemical waste if I toss it out. I wish I could compost it hahaha
